# Send Linux & service basics to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "linux-service-triage", "name": "Linux & service basics", "source": "tencent", "type": "skill", "category": "开发工具", "sourceUrl": "https://clawhub.ai/KOwl64/linux-service-triage", "canonicalUrl": "https://clawhub.ai/KOwl64/linux-service-triage", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/linux-service-triage", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=linux-service-triage", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "references/triage-commands.md" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "linux-service-triage", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-05T00:47:05.380Z", "expiresAt": "2026-05-12T00:47:05.380Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=linux-service-triage", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=linux-service-triage", "contentDisposition": "attachment; filename=\"linux-service-triage-1.0.0.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "linux-service-triage" }, "scope": "item", "summary": "Item download looks usable.", "detail": "Yavira can redirect you to the upstream package for this item.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/linux-service-triage" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/linux-service-triage", "downloadUrl": "https://openagent3.xyz/downloads/linux-service-triage", "agentUrl": "https://openagent3.xyz/skills/linux-service-triage/agent", "manifestUrl": "https://openagent3.xyz/skills/linux-service-triage/agent.json", "briefUrl": "https://openagent3.xyz/skills/linux-service-triage/agent.md" } } ``` ## Documentation ### PURPOSE Diagnoses common Linux service issues using logs, systemd/PM2, file permissions, Nginx reverse proxy checks, and DNS sanity checks. ### WHEN TO USE TRIGGERS: Show me why this service is failing using logs, then give the exact fix commands. Restart this app cleanly and confirm it is listening on the right port. Fix the permissions on this folder so the service can read and write safely. Set up Nginx reverse proxy for this port and verify DNS and TLS are sane. Create a systemd service for this script and make it survive reboots. DO NOT USE WHEN… You need kernel debugging or deep performance profiling. You want to exploit systems or bypass access controls. ### INPUTS REQUIRED: Service type: systemd unit name or PM2 process name. Observed symptom: error message, status output, or logs (pasted by user). OPTIONAL: Nginx config snippet, domain name, expected upstream port. Filesystem paths used by the service. EXAMPLES: systemctl status myapp output + journalctl excerpt Nginx server block + domain + upstream port ### OUTPUTS Default: triage report (likely cause, evidence from logs, minimal fix plan). If explicitly requested and safe: exact shell commands to apply the fix. Success = service runs, listens on expected port, and reverse proxy/DNS path is correct. ### WORKFLOW Confirm scope and safety: identify service name and whether changes are permitted. Gather evidence: status output + recent logs (see references/triage-commands.md). Classify failure: config error, dependency missing, permission denied, port conflict, upstream unreachable, DNS mismatch. Propose minimal fix + verification steps. Validate network path (if web service): app listens → Nginx proxies → DNS resolves → (TLS sanity if applicable). Provide restart/reload plan and confirm health checks. STOP AND ASK THE USER if: logs/status output are missing, actions require privileged access not confirmed, TLS/cert management is required but setup is unknown. ### OUTPUT FORMAT TRIAGE REPORT - Symptom: - Evidence (what you provided): - Most likely cause: - Fix plan (minimal steps): - Exact commands (ONLY if user approved changes): - Verification: - Rollback: ### SAFETY & EDGE CASES Read-only by default: diagnose from provided outputs; do not assume you can run commands. Avoid destructive changes; require explicit confirmation for anything risky. Prefer nginx -t before reload and verify ports with ss. ### EXAMPLES Input: “journal shows permission denied on /var/app/uploads.” Output: path permission analysis + safe chown/chmod plan + verification. Input: “App works locally but domain returns 502.” Output: upstream port checks + nginx error log interpretation + proxy_pass fix plan. ## Trust - Source: tencent - Verification: Indexed source record - Publisher: KOwl64 - Version: 1.0.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-05-05T00:47:05.380Z - Expires at: 2026-05-12T00:47:05.380Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/linux-service-triage) - [Send to Agent page](https://openagent3.xyz/skills/linux-service-triage/agent) - [JSON manifest](https://openagent3.xyz/skills/linux-service-triage/agent.json) - [Markdown brief](https://openagent3.xyz/skills/linux-service-triage/agent.md) - [Download page](https://openagent3.xyz/downloads/linux-service-triage)
